Video “5 reasons for 10 GigE cameras”
10 Gigabit Ethernet – fast, reliable and easy integration
Gigabit Ethernet is the most widely used interface in industrial image processing due to low system costs, cables up to 100 m in length and the GigE Vision standard for easy integration. The ongoing trend toward higher resolution and speed due to ever faster production cycles and new CMOS sensors calls for cameras with increased transmission bandwidth. 10 Gigabit Ethernet allows for transmission of 10 times more image data at 1.1 GB/s while at the same time providing all the advantages of Gigabit Ethernet interfacing without requiring a change to integration software.
High bandwidth for cables up to 100 m
The 10 GigE interface provides stronger solutions for applications requiring high bandwidth for long-distance transmission up to 100 m with a single cable, but eliminates the need for specialized components such as frame grabbers.
Under the label 10GBase-T, the Ethernet standard IEEE 802.3an defines the use of twisted pair cables. CAT6 cables are allowed for up to 55 m distance. Greater distances call for CAT6a cables.
For existing CAT5e installations where replacing the present cabling is economically infeasible, transmission rates of 2.5 or 5 Gbit/s are recommended. Transmission speed is defined in standard IEEE 802.3bz of the NBASE-T Alliance.
High-speed image processing
Precise detection in fast processes
Modern CMOS sensors offer excellent image quality at high sensitivity, low dark noise and a very high dynamic range at high frame rates. Together with the 10 GigE interface, these benefits display their strength in fast processes such as in video applications with up to 4K at 60 fps as well as in motion analysis and in virtual reality applications.
LXT and QXT models by Baumer are high-performance industrial cameras with 10GBase-T interface and the latest CMOS sensors.
Short latency for ever-increasing machine speed
Compared with Gigabit Ethernet cameras, 10 GigE cameras significantly reduce overall system latency – i.e., the delay between the host‘s request and receipt of response. First, sensor reading is much faster which means shorter readout times, and finally the 10 GigE interface speeds up data transmission. The latency also depends on utilized hardware and software components. Unlike Gigabit Ethernet with 50 to 125 μs, the latency per frame is brought down to approximately 5 to 50 μs.
